Simulazione energetica di scenari per la produzione combinata a servizio di edifici civili in area mediterranea

Increasing regulation on greenhouse gas emissions aimed at fighting climate change has significantly boosted construction and architecture sectors. Recent European directives (2010/31/UE e 2012/27/UE) promote the reformulation of energetic planning rules and the adoption of environmental-friendly models including the nearly zero-energy buildings, which can be realised through increased energy efficiency, optimised energy production and the systematic use of renewable energies. In this context, the civil sector plays a key role in both the erection of new buildings and in the retrofitting of the existing ones, especially with respect to energy production. The present work aims at studying plant design technologies and configurations for the combined production in civil buildings, focusing on the problematic energy situation of the Mediterranean region. The study resulted in the development of a calculation code (in Matlab environment) for the energetic simulation of different scenarios of combined production, which used high-efficiency on market technologies based on renewable energies. Comparing different solar energy conversion technologies, co-trigenerative solutions and solar cooling systems for a Mediterranean-like electricity consumption, and using the calculation code herein developed, it was possible to analyse the energetic behaviour and to determine its main environmental and economic-financial parameters. The consequent sensitivity analyses highlighted the significant incidence of energetic costs and of the efficiency parameters of the single technologies, reflecting the substantial differences observed in the final results of the simulations.
